Specification of Letters Patent.

Patented March 17, 1008.

Appication filed August 30, 1907. Serial No. 390,774.

To all whom 'it may concern:

Be it known that I, FREDERICK F. SHUMER, a citizen of the United States,residing at Norwalk, in the county of Huron and State of Ohio, haveinvented new and useful Imrovements in Tooth-Brushes, of which theollowing is a specification.

This invention relates to tooth brushes, and it has for its object toprovide `a sim le, convenient and efficient device of this c ass inwhich the handle of the brush shall constitute a reservoir for theliquid, powder, paste or other material, detergent or other- Wise, whichis utilized for the purpose of cleansing the teeth; further objectsofthe invention being to simplify and improve the',

construction and operation of this class of devices.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same con-y sists inthe improved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,

ut that changes, alterations and modiiications Within the scope of theinvention may be resorted to when desired.

In the drawing, Figure' 1 is a side elevationl of a tooth brushconstructed in accordance with the invention. Fig. 2 is a longitudinalsectional View of the same:

Fig. 3 is a longitudinal sectional view of a l portion of the brushshowing the discharge tube in position fordischarging a portion of thematerial contained in the reservoir within the handle. Fig. 4 is atransverse sectional view of the handle taken on the plane indicated bythe line 4-4 in Fig. 2.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved tooth brush comprises 'the head section A having the shankB, and the tubular handle section C, which constitutes a reservoir forthe cleansing material, and which is detachably connected with the shankof the head section as will be presently more fully explained.

The head section A and the shank B include an integral back piece 1 atone end of which the bristles 2 are mounted and secured pug 7. ug or`flange 14 a in any suitable well known manner. The opposite end of theback iece 1 constitutes a sleeve 3, the extremity o which is externallythreaded, at 4, and is screwed into one end of a tube 5, made of metalor other suitable material and which constitutes the body of the handlesection C; said tube 5 also constitutes a receptacle for cleansingmaterial which mayconsist of li uid, powder or paste of any description.T e outer end of the tube 5 constitutes the handle section, wherebyismeant the end opposite to that into which the sleeve 4 is inserted,and is provided With a screw threaded cap 6 consti tuting a closure.

The end of the sleeve 4 which is connected with the tubular handlesection is provided with a plug 7 having a central aperture 8 wherein istted a slidable dischar e tube 9 having at its outer end a spherica bulbor enlargement 10 wherein is fitted a ball 11 formed at the inner end ofthe extension tube 12 which is thus connected with the discharge tube 9in such a manner as to be capable of universal movement with relationthereto.

The discharge tube 9 together 'with the extension tube 12 is forced awayfrom the plu 7 by the action of a spring 13 which is coile u on the tube9 between' the bulb 10 and the The back iece 1 is provided with ad)jacent to the bristles 2,

said lug or flange being provided with a recess wherein is seated awasher 15 adapted to be engaged by the outer extremity of the extensionl2 of the discharge tube. It will be observed that the extension tube 12is exposed in such a manner as to be readily grasped by the fingers ofthe operator, who, by seizing said tube' may press the latter and thedischarge tube 9 against the tension of the spring 13 until the outer orfree end of the extension tube 12 may be disengaged from the washer 15and lowered to the sition shown in Fig. 3 of the drawings, w en, byproperly shalingand manipulatin the brush, a portion of t e contents oft e tubular handle may be readily discharged through the tubes 9 and 12and onto the bristles ofy the brush. When a sufficient uantity of thecleansing material has been ischarged, the discharge tube 9 and itsextension member 12 may readil be restored to the position shown in Fig.2 o the drawings, with the dischar e end "of the extension memberengaging t e washer 15, which latter may thus be.

regarded as constituting a closure for the receptacle containing thecleansing material. The discharge tube will be retained in closedposition by the pressure of the spring 13, as will be readilyunderstood.

When 'the cleansing material contained in the tubular section is inliquid or in A owder form, it may be readily shaken out t ough thedischarge tube and -through the extension member of the latter; but whenthe said cleansing material is in the form of a aste, it will be founddesirable to use specia means for discharging the same, said specialmeans being constructed as ollowsz-,A longitudinally movable follower2() is arranged in the tubular handle section, 5, said follower beingprovided with laterally extending lugs 21 engaging longitudinal grooves22 in the tubular member 5, to revent the follower from turning within te latter. An operating screw 23 is swiveled, or sup orted for rotationin the ca 6, said screw eing pr ovided with a hand e 24 by means ofwhich it may be conveniently rotated for the purpose of effectingadjustment of the follower 20, which latter has a longitudinallythreaded aperture 25 engaging the screw 23. The

latter is provided with a terminal disk or button 26 to reventdisengagement of the follower; and it also has an annular ilange orcollar 27 abutting u on the inside of the cap 6 for the purpose oretaining the adjusting screw in posit1on relative to said cap.

It will be readily seen that when the follower 20 is in position closelyadjacent to the ca 6, the tubular handle may be filled with a etergentpaste, by separating said handle fromthe shank B with which, ashereinbefore stated, it has threaded connection. After `re-assemblingthe parts, the contents of the tubular handle section may be dischargedthrough the discharge tube 9 of the extension tube 12 by manipulatingthe screw to operate the follower 20, as will be readilyunderstood.

From the foregoing description taken in connectionwith the drawingshereto annexed, the operation and advantages of this invention will bereadily understood, lt is simlple in construction, inexpensive andthoroug ly efcient for the purposes for which it is provided; beingespecially useful for travelers and tourists in enabling a supply ofcleansing material to be conveniently carried in the brush handle, anddischarged from the latter as it is needed for use.

Having thus fully described the invention, what is claimed as new is lc 1. A brush having a tubular handle member constituting a receptacle, atubular shank detachably connected therewith, a tubular discharge membermovable in the tubular shank and having an extension connected theretoby a ball and socket joint, and a stationary closure for the free end ofthe exten` sion oi the tubular discharge member.

2. A brush having a tubular handle member constituting a receptacle, atubular shank de tachably connected therewith, and having an aperturedplug, a s ring actuated discharge tube longitudinally movable in thetubular shank, a tubular extension member connected with the dischar etube for universal movement with relation thereto, and a stationarybrush.

3. A brush having a tubular handle .mem-y ber constituting a receptacle,a tubular shank connected detachably therewith, and a tubulars ringactuated-discharge member seated for ongitudinal movement in the tubularshank, said discharge member includin a discharge tube and an extensionmem' er connected therewith for universal movement and a closure for thedischarge member consisting of a liange stationary on the shank and anelastic washer supported upon said flange.

4. A brush having a tubular handle member constituting a receptacle, atubular shank detachably'connected therewith, and having an aperturedplug, a spring actuated tubular discharge member longitudinally slidablein the tubular shank, a follower movable longitudinally in the tubularhandle member, a threaded cap constituting a closure for the latter, andan operating screw supported for rotation in the cap and having threadedengagement with the follower.

In testimony whereof I afIiX my signature in presence of two witnesses.

FREDERICK F. SHUMIER.
